The little girls at the elementary school where I have my office:) I'll take it where I can get it, but their comments are the sweetest.
I work with children through eighth grade and while the middle school kids are muuuch too cool to notice anything beyond their peers, the elementary age children have more to say.
It's too cute when you pass two 7 year olds walking down the hall and they whisper (indoor voice, of course, LOL) "I like your shoes."
